Line 3173 pipeline maintenance; Mar 7 thru Mar 10 EPNG will be performing

schedule Mar 7 thru Mar 8

The following locations will be unable to flow during the maintenance Mar 7

The Enterprise GE primarily compresses Enterprise (IMLWAHA) deliveries to EPNG
and supplements the compression of EPNG Waha deliveries.  

No compression will be available at Waha, receipts into the EPNG pipeline will
be dependent on the individual interconnects pressures.  Deliveries from EPNG
will be limited by line pressure. IMLWAHA will not flow Mar 7 thru Mar 8.  

Capacity through segment PUCWAHA will be set to zero thereby requiring gas from
ITERRELL, IMLTERPK and IYUCBUTE to be re-routed to the Wink compressor station
thru Line 2000 instead of the Waha compressor station and the sum of these
receipt locations will be limited to a total of 98 MDth/d.
